"I commend the teamwork and courage of everyone involved in this incident, from the rescuers who fearlessly ran into the water to our officers and firefighters who executed the car removal (Saturday)," Arlington police Chief Frederick Ryan said.

Joyce will not face any criminal charges, but police said they would make an immediate threat notification to the RMV, which will trigger a review into her ability to drive safely.

Her husband said she is recovering well and will be released from the hospital by Sunday morning.
